CVE-2026-82612: Online Medicine Delivery System SQLI Flaw

CVE-2026-82612 Overview

CVE-2026-82612 is a SQL injection vulnerability in itsourcecode Online Medicine Delivery System 1.0. The flaw resides in the loadResultList function of the Product Detail Page component, reachable via /index.php?q=single-item. Attackers can manipulate the ID parameter to inject arbitrary SQL statements into backend database queries. The vulnerability is remotely exploitable without authentication or user interaction. A public disclosure of the exploit technique has been released, increasing the risk of opportunistic exploitation against exposed installations. The weakness is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component.

Critical Impact
Unauthenticated remote attackers can inject SQL statements through the ID parameter, potentially exposing patient records, medicine inventory, and administrative credentials.

Technical Details for CVE-2026-82612

Vulnerability Analysis

The vulnerability exists in the loadResultList function used by the Product Detail Page of the Online Medicine Delivery System. The function accepts the ID request parameter and incorporates it directly into a SQL query without proper sanitization or parameterization. Because the endpoint is reachable over the network and does not require authentication, an attacker can issue crafted HTTP requests to trigger the injection. Successful exploitation allows manipulation of database queries used to render product detail information. Public disclosure of the technique means proof-of-concept payloads are already documented in third-party vulnerability repositories.

Root Cause

The root cause is the lack of input validation and use of dynamic SQL concatenation inside loadResultList. User-supplied values from the ID query parameter flow into a database query without being bound as parameters or escaped. This violates secure query construction practices and enables the injection primitive described in [CWE-74].

Attack Vector

Exploitation requires only network access to the vulnerable application. An attacker submits a GET request to /index.php?q=single-item with a malicious ID value containing SQL syntax. The injected payload modifies the intended query, letting the attacker read database contents, enumerate schema, or extract sensitive records depending on database privileges. Because no privileges or user interaction are required, automated scanners can identify and abuse affected instances at scale.

Detection Methods for CVE-2026-82612

Indicators of Compromise

HTTP requests to /index.php?q=single-item where the ID parameter contains SQL metacharacters such as single quotes, UNION SELECT, SLEEP(, or comment sequences like -- and #.
Web server logs showing repeated requests to the single-item endpoint from a single source within a short time window.
Unusual database errors or query timeouts correlated with requests carrying non-numeric ID values.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the ID parameter of the single-item route for SQL injection signatures.
Enable database query logging and alert on queries against product tables that include tautologies (for example, OR 1=1) or stacked statements.
Correlate HTTP 500 responses from /index.php with subsequent successful responses that return abnormally large payloads, which can indicate blind or UNION-based extraction.

Monitoring Recommendations

Forward web server and PHP error logs to a centralized SIEM for pattern-based analysis.
Baseline normal ID parameter values (typically small integers) and alert on deviations.
Monitor outbound database connections and query volumes from the application host for anomalies consistent with mass data extraction.

How to Mitigate CVE-2026-82612

Immediate Actions Required

Restrict network exposure of the Online Medicine Delivery System by placing it behind a WAF or VPN until a fix is verified.
Audit web server logs for prior exploitation attempts targeting /index.php?q=single-item.
Rotate database credentials and administrative passwords if evidence of injection is present.

Patch Information

No official vendor patch has been referenced in the CVE record at the time of publication. Administrators should monitor the itsourcecode project page and the VulDB Vulnerability Overview for updates. In the absence of an upstream fix, apply source-level remediation by rewriting loadResultList to use parameterized queries or prepared statements and validating that ID is a strict integer before use.

Workarounds

Add server-side input validation that rejects any non-numeric value for the ID parameter before it reaches the database layer.
Deploy WAF signatures blocking common SQL injection payloads on the single-item route.
Apply least-privilege permissions to the database account used by the web application so that injection cannot access administrative tables or execute file operations.

bash

# Example WAF rule (ModSecurity) to block non-integer ID values on the vulnerable route
SecRule REQUEST_URI "@rx /index\.php\?q=single-item" \
  "chain,phase:2,deny,status:400,id:1082612,msg:'Blocked non-integer ID (CVE-2026-82612)'"
SecRule ARGS:ID "!@rx ^[0-9]+$" "t:none"
